Tetrasodium Glutamate Diacetate
INCI · Tetrasodium Glutamate Diacetate · also GLDA
Overview
A chelator that binds trace metal ions in a formula. Those ions arrive with water and raw materials and quietly catalyse oxidation, so tying them up helps a product keep its colour, scent and active content over its shelf life. It is derived from fermentation-sourced glutamic acid and is readily biodegradable.
Who it's for
Anyone using a product that contains an easily oxidised active, and anyone who prefers a formula that avoids EDTA on environmental grounds.
Cautions
It has no action on skin and does not preserve a product against microbes; it supports whichever preservative system is doing that job. A chelator in the list says something about formulation care, not about efficacy.
